The mobile application (App) industry has grown tremendously over the past five years,

primarily fueled by small App development businesses. Lacking advertising budgets, these

relatively unknown, small businesses often offer free versions of their paid Apps to reduce

customer uncertainty about App quality and get noticed in the crowded App industry. In this

research we investigate the implications of offering free versions on the adoption speed of paid

Apps by building on the existing marketing and information systems literature on sampling and

versioning. We use a unique dataset of 9 million observations from 13,764 Apps for our analysis.

We find that while the strategy of offering free versions of paid Apps is popular, it impacts the

adoption speed of paid Apps negatively and this impact is stronger in the later life stages of paid

Apps. We also find that the negative impact of offering free versions on the adoption speed of

paid Apps is lower for utilitarian Apps. We expect that the results of our study will enable App

developers to make informed decisions about offering free versions of paid Apps and prompt

academicians to produce more work focusing on this industry.
